Executive SummaryUpdated on Nov 2, 2025

Azure Container Registry and Amazon ECR are key players in the container registry service market. Azure Container Registry has a lead in security features and integration with Azure, while Amazon ECR is preferred for user-friendliness and AWS integration.

Features: Azure Container Registry offers role-based access control, geo-replication for global deployments, and vulnerability scanning. Amazon ECR provides seamless AWS service integration, image scanning for vulnerabilities, and is recognized for its user-friendly interface.

Room for Improvement: Azure Container Registry could enhance accessibility, automate scanning processes, and improve downtime reliability. Amazon ECR needs more comprehensive documentation, better third-party service integration, and a more user-friendly UI.

Ease of Deployment and Customer Service: Azure Container Registry and Amazon ECR support both public and private cloud deployments. Azure's customer support receives mixed reviews, while Amazon ECR benefits from consistent and reliable AWS support.

Pricing and ROI: Azure Container Registry offers varying pricing tiers and is slightly more expensive but justifiable with its Azure integrations. Amazon ECR’s pay-as-you-go model is budget-friendly and suits those invested in AWS.

Senior Project Manager at NTT DATA

Solution delivers consistent reliability and high stability

ECR is reliable, however, I don't consider it the best container registry available. The main reason is that it is not entirely based on the original Docker registry. For instance, I prefer Azure's ACR because, in ACR, there is no need to create repositories; I simply push. Logging into the repository and specifying the path automatically creates everything. This structure resembles an S3 setup with a container registry layout.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The autoscaling functionality is the main beneficial feature of Amazon ECR. It simplifies management, but some configurations can complicate things a bit."

"What I like most about Amazon ECR is that it's swift."

"The most valuable feature is that Amazon ECR is very simple and useful."

"The most valuable feature of the solution is the scanning of images for vulnerabilities."

"In the case of Amazon ECR, there are various valuable features we can see. Currently, there are image-scanning capabilities that we use."

"Amazon ECR has a native integration with all AWS services, making it convenient for use within the AWS ecosystem."

"The solution is very stable."

"There are no issues. The service is remarkably stable."

More Amazon ECR pros

"Specific tokens can be used to set folder structure or restrict things like read or write access."

"The whole package is valuable as it allows for easy application cloning and deployment."

"It's running behind a big financial and legal customer, who runs Service Fabric behind a front door, servicing local banking containers on an ISV solution developed internally."

"Azure Container Registry is an easy-to-install, easy-to-configure, and easy-to-deploy solution."

"The solution has built-in resiliency and replication zone availability so it is very stable."

"Azure Container Registry can be used to detect vulnerabilities in your image."

"Pricing is reasonable."

"What I like best about Azure Container Registry is that it's fast. It also has 24 x 7 reliability. I didn't face any downtime issues using Azure Container Registry. I also like how secure the solution is, especially as it's from Microsoft."

More Azure Container Registry pros

Cons

"Amazon ECR should include integration with Docker Hub."

"There could be improvements to the interface of AWS concerning ECR."

"Deeper integration with other security tools would enhance usability."

"There were some initial connectivity issues, especially when accessing ECR from our on-prem setup."

"The Amazon ECR interface could benefit from improvements to enhance user experience."

"It would be great if they could also provide a reference to fix the errors or vulnerabilities in the images rather than just notifying us about them."

"I suggest making it more aligned with the Docker registry version two API specification."

"If there were a way to use containers as tasks directly, that would simplify things. Currently, when we use EC2 instances, scaling horizontally means increasing the instance count by five times, which might not be cost-effective. Maybe using containers directly for tasks could be a better option."

More Amazon ECR cons

"The security, dashboards, and monitoring system could be improved."

"There is a need for a graphical interface instead of writing code in Visual Studio to create images."

"Lacks the option of having access keys stored in a master key vault."

"Implementation needs improvement. We have a lot of open, online sources. Doing a deployment is easy for us. The only issue is when we have VPN connections and we try to pull the images from Container images to the local Dockers, it slows down."

"We have not explored geo-replication features."

"The accessibility of Azure Container Registry also has room for improvement because the solution is not always accessible 24 x 7. I experienced this three times when the service wasn't responding, so I could not push or pull images, and I had to decommission Azure Container Registry and redeploy it."

"It's not an open source, and we pay per hour to Microsoft Azure."

"We have found that it is sometimes difficult to pull images from the host application."

More Azure Container Registry cons

Pricing and Cost Advice

"My company currently has Amazon ECR under the pay-as-you-go model. The tool is more affordable than Azure Container Registry, and it's worth the money."

"The solution's prices are high in India as compared to the US."

"Amazon ECR does not have a high cost."

"The main difference between Amazon ECR and other solutions, like Google Kubernetes Engine, is that I haven't personally used GKE. However, I know that GKE costs around $60 per month, which is quite cost-effective."

"The product is expensive."

"The solution's price is reasonable compared to its competitors"

"Azure is a bit expensive."

"I have no information on how much Azure Container Registry costs. I know it's the only solution my institution can use, so the cost was approved."

"The product is competitively priced."

"I would rate the pricing four out of ten."

"Azure Container Registry, has no cost, but you pay for storage service."

"When using Azure Container Registry, it was $1.5 or $1.6 per day, but I'm unsure how much it costs today."

"The Premium version includes some enhancements but is still quite okay with regard to pricing."
